Getting tired of dealing with empty calibration gas cylinders? PortaGas makes it easy and convenient with PortaGreen. Each cylinder comes with a prepaid return-shipping label. Once the cylinder is empty, simply strip off the shrink-wrap to reveal the prepaid FedEx return label and hand it off to your shipper.
